Summary
Content
The energy systems of the future are increasingly
decarbonized, distributed and digitalized.
Environmental aspects have to be considered during
planning and operation.
With our recent developments and innovative
solutions for arc suppression coils (ASC) and earth
fault compensation controllers we can support future
proof investments four our customers.
These are alternative insulation media, an improved
drive concept, an earth-fault compensation controller
that has been integrated directly into the motor
control cabinet of the coil, and the Senscoil
technology as part of Sens Product suit.

Coil StoryArc Supression Coil (ASC)

Coil 1.0 Petersen Coil / Arc Suppression Coil
How everything got started
100 Years of Resonant Grounding was
celebrated 2 years ago….
1917 Waldemar Petersen receives a patent for
an inductivity between star point and Earth, which
conducts a current equal or similar with the
capacitive earth fault current. During the following
decades arc suppression coils are installed
worldwide up to 230 kV. At the begin the
adjustment of the inductive current is done
stepwise only (step coils).

Coil 2.0 Arc Suppression Coil with Plunger Core
Stepless tuning manually and later with controller
1938 The first stepless adjustable arc
suppression coil is build with the plunger core
principle. The tuning is done manually with
auxiliary equipment to determine the
compensation degree.
1950 The first electromechanical resonance
controller was built for automatic adjustment of
the arc suppression coil.
1981 The first microprocessor controlled
resonance controller was built by Spezielektra
(Trench Austria)

Coil 4.0 Solutions for tomorrow
Based on extensive experience in design,
construction and application of ASCs, Trench
products can meet the most stringent
requirement for earth-fault compensating
techniques. But we never stop to improve design
and our search for new ideas and technologies.
The latest result is…
Coil 4.0
▪ Fast Drive
▪ Biodegradable Oil
▪ Integrated Controller

Fast Drive
The motor drive unit serves for adjustment of the
air gap of a plunger core type ASC according to
the operational needs.
The rated power of the new motor drive unit will
have 3 kW.
The running time between the upper and lower
end position is now reduced to 1 minute.
Benefit of Solution:
The average time to reach a new well tuned
position (resonance point) is 20 seconds. In the
growing networks this will be an operational
advantage.

Biodegradable Oil
In addition to the transformer oils on naphthenic
basis, inhibited or non inhibited, according to IEC
60296:2003 water pollution class 1, and MIDEL
7131 synthetic Ester fluid, according to IEC
61099 water pollution class 0, we are now able
to provide an alternative to mineral oil and
synthetic ester in using natural ester as
insulation fluid.
For the proof of concept in an ASC application we
have tested MIDEL eN 1204 (rapeseed based)
and MIDEL eN 1215 (soybean based) as well as
FR3 from Cargill (vegetable oils). We decided to
use the FR3 based on customer preferences for
pilot project.

Biodegradable Oil
Advantage High Fire Point
High fire point provides safer, more reliable grid
performance
FR3 fluid has a fire point of 360°C, more than
twice the fire point of mineral oil. This improves
the fire safety for any ASC application.
With this improved fire safety, utilities can:
1. Reduce clearances to buildings and equipment
2. Eliminate the need for more costly fire
mitigation systems
3. Potentially reduce insurance premiums and
liability reserves

Biodegradable Oil
Advantage Thermal Capabilities – Asset Life Extension
This higher temperature capability enables:
• Slower rate of cellulose ageing than mineral oil
• Longer cellulose lifetime at standard
temperatures
• Option to run at a higher temperature, for a
standard lifetime
• Provides a higher power output, without the
need for high temperature insulation
• Design of smaller ASCs possible -> that could
use less fluid and less construction materials

Biodegradable Oil
Advantage Environmental Benefits
Readily biodegradable, non-toxic helps protect
the environment
▪ Made from 100% renewable vegetable oil
▪ Readily biodegradable (28 days)
▪ Non-toxic in both oral toxicity tests and aquatic
toxicity tests
▪ Contains no petroleum, halogens, silicones or
sulfurs
▪ Has a reduced carbon footprint – 56x less
carbon emissions than mineral oil 0

Biodegradable Oil
Implementation Challenges
Design requirements to make this technology fit
for use in ASC applications:
▪ Heater (3 kW) for very low outside temperature
to guarantee the needed difference of 10 K to
the pure point. For ester products with lower
pourpoint (Midel eN 1204 –31°C) ongoing
research if the heater can be omitted
▪ Rubberbag to avoid oxidation of the natural
ester during breathing
▪ Sealing material Viton is used from DuPont
instead nitrile butadiene rubber (NBR)

Integrated Controller
All-in-one
The controller unit is installed in the control
cabinet mounted on the side wall of the ASC
tank.
Benefit of Solution:
▪ All-in-one solution, very fast plug&play start up
▪ Control unit ready wired in factory
▪ Calibration for min/max position and
linearization done in factory
▪ Less cabling to control room
▪ Reduced or no commissioning on site needed

General Principles
Connectable & intelligent
• All Sensgear products using same IoT device to
connect to the cloud
• The IoT device only collects data from the sensors
for transmission to the cloud – no on site
calculations
• By default data transfer to a cloud via GSM or on
customer‘s request transfer to on site customer IT
infrastructure possible
• Digitalized products to optimize operations
• Future is in managing and learning from the data
• Software applications for further value creation
and operational enhancement (e.g. predict asset
life time, for short time duty ASCs calculation of
remaining service time)
